How to upgrade both WLC configured in HA

Hello team,

I need to upgrade both the standby and active WLCs using the CLI. However, I couldn't find the method to upgrade the standby WLC via CLI in the official Cisco documentation. Could you please share the procedure? I believe the standby WLC has a limited set of accepted CLI commands and has no GUI, so I want to confirm how to transfer the image to the standby WLC and perform the upgrade via CLI.

Additionally, since I have to upgrade both WLCs (active and standby) individually, won't there be a version mismatch after upgrading the first one? Could this mismatch affect the HA setup?

I am working with 9800 WLCs configured in HA mode (active and standby) that manage over 1,000 APs. What is the recommended approach to upgrade the software in this setup?
